So this is was my second test with the Arduino. I first started to work on a small CharliePlex demo and quickly moved to the SparkFun LED Matrix. I got the RG first - and this was the result of my experimentation.
Thanks to many on the Forum for code insights, help and pointers!

The one part I think I did weird was the shifting of data from right to left - where I took an array and did a loop to move each value down one. I know there is a better way but I am just getting up to speed on my byte math!
I'll try to post my code online once I get it all neat and pretty!
